Gemma 4 12B Unified

Gemma 4 12B Unified accepts about 262K tokens of context. That only matters if you routinely send very long documents, large codebases, or multi-turn histories that approach that limit.

Gemma 4 12B Unified is a balanced tier from Google. It suits self-hosted multimodal applications, text generation, instruction following. Thinking is enabled by <|think|> in the system prompt; omit it to disable. Disabled thinking still emits an empty thought block. Use temperature=1.0/top_p=0.95/top_k=64. Omit historical thoughts except during tool-call turns. Video understanding processes frame sequences; audio is ASR/speech-to-translated-text, not speech generation. Native text context comes from this checkpoint’s text_config, not the vision encoder’s positional limit. Exact hard output cap and universal hosting rates remain unknown; example generation budgets are not caps. Vendor benchmark runs remain unranked until identity/settings are reconciled.

Gemma 4 12B Unified publishes open weights, but self-hosting depends on the licence, hardware footprint, quantisation quality, and serving stack. A hosted API is often cheaper until you have measured throughput and concurrency on your own hardware.
